NON-REFILLABLE BOTTLE.

To all whom it may concern:

Be it known that I, J OHN BERG, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to non-refillable bottles, and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claim.

The object of this invention is the ,production of an efiicient and serviceable bottle which, after it has been once filled cannot be refilled without destroying the bottle or at least mutilating it to such an extent as to prevent its reuse as an original package, and in order to accomplish this object at the least expense over an ordinary bottle, the parts constituting this bottle are comparatively simple and can be produced at a minimum cost.

In the drawings already referred to, which serve to illustrate this invention more fully, Figure l is a longitudinal sectional elevation of my improved bottle. Fig. 2 is a plan of the same, the neck being removed. Fig. 3 is a view of a portion of the upper end of the neck; and Fig. 4 is a sectional view of fragments of the bottle-body and the neck showing the shut-off valve in its open position.

Like parts are designated by corresponding symbols and characters of reference in all the figures.

A in these drawings designates the bottle body, and B, the neck. This bottle-body may be of any special or particular design or configuration, but in its top 10 there must be an upwardly-projecting tubular boss 11, which by preference is internally screw-threaded and has a shoulder 12, pierced by a central passage 13, this bein the only requirement which my improve bottle needs over an ordinary bottle. The neck B may also be of any external design Specification of Letters Patent.

lower end an external screw-thread 14, adapted to engage the internal screw-thread in the boss 11, and a shoulder 15, by which the neck B bears upon the shoulder or upper edge of the boss 11, the screw-threaded portion of the neck being shorter than the internal screw-thread in the boss to permit of the locating therein of an annular valve-seat 16, and above the same, of a valve proper 17, there being secured to the latter a, preferably hollow, cap 18, in any suitable man ner. This valve-seat is molded in glass, hardrubber, celluloid, vulcanite or other suitable material, but the valve proper is preferably made from leather, soft rubber, or other analogous material.

The top-portion of the neck B is solid, and in this portion there is a vein or passage 19, serving as means to admit air to the bottle when its contents are being drawn, and it also has a discharge-passage 20, from which the liquid is discharged. To this dischargepassage 20 lead a series of obliquelyarranged, rather small, passages 21, from the interior of the neck, these passages or veins being obliquely arranged to prevent a wire or other instrument being passed through the discharge-passage into the neck of the bottle to open the valve proper or otherwise interfere with the proper functioning of the device. 7

There is formed around the opening 20 on the outside of the bottleneck a bead 22, serving as a nozzle to prevent the liquid when being poured from running down the outside surface of the neck and to facilitate pouring.

Over the upper end of the neck B there is placed a flexible, cup-shaped, cap C, which cap extends downwardly far enough to normally cover the discharge, and the ventopenings and it has at its lower edge a bead 23, so that when the cap C is pushed upwardly by pushing against the head 23, the sidewall or rim of said cap will curl or roll up, as shown in Fig. 3, thereby exposing both, the discharge and the vent openings, while when turned back to the normal position, the passages are hermetically sealed.

To pour liquid from the bottle, the same is tilted so that the valve proper 18 can open sufficiently to allow the liquid to escape through the central opening in the valveseat, the hollow valve-cap 18 resting on the inner wall of the bottle-neck, as shown in Fig. 4, the valve, however, not opening sutficiently to prevent its rapid closing as soon as the bottle is placed in an approximately vertical position.

In actual use, the neck 13 being a separate part of the bottle, the latter can be readily filled through the opening 16, after which the valve-seat and the valve proper are placed in position. The screw-threaded part of the neck B is then dipped into a liquid,

such as silicate of soda or potassium, Canada balsam, or other suitable cement and screwed into the bottle, when, after the cement has hardened, these two parts are so firmly united that they can no longer be separated without destroying one or the other or both parts.

To conceal the joint at the junction of the bottle-body and the neck, I prefer to paste a label over the adjacent portions of said neck and the boss, which for this purpose are made of equal diameter and straight-sided.

It will now be observed that the construction of this bottle is extremely simple and that the few parts of which it is composed may be very cheaply produced so that this improved bottle is but a trifle more expensive than a common bottle of a like capacity, and scarcely any more than a bottle that has a stopper permanently attached.

For original packages, it might be desirable to place into the outer end of the discharge-passage a cork 26, as shown in Fig. l, the outer surface of said cork being flush with the outer edge of the bead 22 around said discharge-passage 20.

Many minor changes in the details of construction of the parts of this non-refillable the latter, an annular valve seat seated on said shoulder and having its central portion pressed outwardly and formed with a central opening, a valve member composed of a ring-like part seated on top of said valve 7 seat and a circular central part whlch 1s connected to the ring-like part by an integral part of each, said central part seating on the outwardly pressed part of the valve seat, a hollow cap having its bottom seating on the top face of said central part of the valve, and means for rigidly connecting said hollow cap and said central part of the valve, and an externally threaded neck port-ion which engages said boss and seats on the ring-like part of the valve.

In testimony that I claim the foregoing as my invention, I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN BERG.
